The rest of my editors: Kezia Endsley, Bryan Gambrel, and the Technical Editor, Tim Moore, kept me on track so the readers can have an accurate and readable text. The Tulsa Junior College administration continues to be sup- portive of my writing. More importantly, Diane Moore, head of our Business Services Division, Tony Hirad, and Elaine Harris, are friends who make teaching a joy and not a job. As always, my beautiful bride Jayne, and my parents Glen and Bettye Perry, are my closest daily companions. It is for them I work.
